Prof RRrgten, a German oleGtTi0iRu, has
deyiHed q telephone "siTonn which consists
Of o disk capable Of being rapidly reyolyod /.
On the face Of the disk number OF bar mag
Getsare fastened ra9ially 9nd near them % N N

disk is rey0lYed the rapid passage Of the
telephone induces currents in the coll and
these are heard Hs a musical note in a second
| telephone connected In circuit with the coil.
The note heard depends on the arrangement
of the magnet poles on the disk, the puinbeE
